Causes

Acquired tracheomalacia is very uncommon. Rarely, babies, infants, and adults may develop the condition. It occurs when normal cartilage in the wall of the windpipe begins to break down.

Acquired, or secondary, tracheomalacia may result:

From pressure on the airway by large blood vessels

As a complication after surgical repair of a tracheo-esophagela fistula or esophageal atresia

After having a breathing tube or tracheostomy for a long time

Symptoms

Breathing problems that get worse with coughing, crying, or upper respiratory infections

Breathing noises that may change with position and improve during sleep

High-pitched breathing

Rattling, noisy breaths

Exams and Tests

A physical examination confirms the symptoms. A chest x-ray may show narrowing of the trachea when breathing out. Even if the x-ray is normal, it is needed to rule out other problems.

A procedure called a laryngoscopy is used to diagnose the condition. This procedure allows the otolaryngologist (ear, nose, and throat doctor, or ENT) to see the structure of the airway and determine how severe the problem is.
